||Look for any signs of water intrusion.
||Look for proper wiring connections/connector seating.

||Most vehicles equipped with a keypad incorporate a security feature called Anti-scan mode. Inform customer they have 7 attempts at inputting a valid keycode before the keypad will be locked out for one minute. (Only the lock function operates while in this mode). This one minute anti-scan mode is indicated by the keypad light flashing rapidly.
||On 2004 Heavy Duty F-Series repairs, note that the vehicle is released with a new wireless keypad (RF). If the wireless keypad or any remote transmitter requires programming, ALL devices must be present and programmed during the same programming procedure.
